MANGO SHIELD SCALE ( Coccus acuminatus Sign.) 
Florida G.F'. Moznette (April 5): This scale has been very abundant this 
past winter on mango trees, particularly where the trees have not 
been properly sprayed with the oil-emulsion applications during 
the winter. This is especially true in grovps where Bordeaux 
spraying is generally practiced in the bloom which apparently 
promotes scale infestation by/the friendly fungi.

DICTYOSPERMUM SCALE ( Chrysomphalus dint yes perm i Morgan) 
Florida G. F. Moznette (April 5): The Dictyospermum scale was abundant 
on avocado trees in some nurseries. 
PYRIFORM SCALE ( Protopulvinaria pyriformis Ckll.) 
Florida G.F. Koznette (April 5): This insect has played the usual amount 
of damage in avocado groves. 
ORANGE LE/F-NOTCHER ( Artipus florid anus Horn) and 
CITRUS ROOT FEEVIL ( Pachnaeus litius Germ.) 
Florida G* F. Koznette (April 5): Has been very abundant in some localities 
doing some damage to the young growth of avocado trees in young 
groves . In some instances the young growth of young Guatemalan 
avocadoes was observed completely stripped and the weevils went so 
far as to gnaw severely into the young shoots. 
AVOCADO LEAF- ROLLER ( Gracilaria rerseae Busck) 
Florida G . F. Moznette (April 5): This leaf- roller is commencing to work 
in considerable numbers in young groves where trees are putting out 
a good spring flush. 
AVOCADO BLOSSOM THRIPS ( Frankliniella cephalicus Craw.) 
Florida G. F. Moznette (April 5): During the latter part of March, as well 
as at this time of the year while the avocado is in full bloom and 
setting its fruit, this thrips has been exceedingly abundant, and 
in a number of localities has materially damaged the bloom. The 
Pollock and Trapp varieties and some seedlings resembling these 
varieties are especially subject to the work of this species. In 
some instances it is estimated that the damage to bloom is from 60 
to 70 per cent. 
AVOCADO LEAF THRIPS ( Heliothrins haemorrhoidalis Bouche) 
Florida G. F, Moznette (April 5): During the period when the avocado red 
spider is working, this thrips is also to be found in some sections 
of southern Florida which are favorable for it to carry on its 
depredations . These localities are situated generally near the 
ocean, bays, or inlet areas. Avocadoes growing on the keys are 
more generally attacked by this thrips . This species was abundant 
in the above sections during the past winter and the weather conditions 
apparently were likewise favorable. This thrips also contributes 
to the drain of sap from the dormant foliage and often weakens a tree.
